This recently split species is very poorly known. There are very few, if any, recent records, and its tolerance of habitat degradation is not known. For these regions it is classified as Data Deficient. Although it is probably more common than currently thought, it is likely to be worthy of threatened status, and requires urgent research.
Micromacronus leytensis (Sibley and Monroe 1990, 1993) has been split into M. leytensis and M. sordidus following Collar (2006).
Identification. Small in size with elongated, erectile feathers on back and sides. Sexes similar. Bill dark horn, lower mandible lighter. Eyes red; legs greenish-grey; toes straw yellow. Similar species. May be confused with Lovely Sunbird which has a longer, slightly decurved bill and lacks long erectile feathers. At higher altitudes overlaps with Mountain Leaf Warbler which is larger and lacks erectile feathers. Voice. not recorded.
